Abstract
Abstract Improved devices are described for combined sampling and culturing to enable a measure of the microorganism content of a liquid sample. The preferred structure is a long thin tube (e.g., a disposable sterile, transparent, pre-plugged serological pipette) having internal area thereof coated with a culture medium.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
104 words
A DEVICE FOR THE DUAL PURPOSES OF SAMPLING A LIQUID AND CULTURING MICROORGANISM PRESENT THEREIN COMPRISING IN COMBINATION: A. CONTAINER CUP DEFINING A FIRST VOLUME FOR RECEIVING AND CONTAINING A LIQUID AND HAVING CLOSURE MEANS THEREFOR AND B. A TRANSPARENT TUBE HAVING AN OPEN END AND A CLOSED END REMOVABLY AND SEALABLY CONNECTED AT ITS OPEN END TO SAID CLOSURE MEANS AND PROJECTING OUTWARDLY THEREFROM, C. AT LEAST ONE LAYER OF STERILE SOLID NUTRIENT MATERIAL FOR THE GROWTH OF MICROORGANISMS COVERING THE INSIDE SURFACE AREA OF SAID TUBE AND DEFINING A SECOND VOLUME, SAID SECOND VOLUME BEING IN FLOW COMMUNICATION WITH SAID FIRST VOLUME.
